ful Improvements in (looking Vessels, of which the following is aspecification, and which are illustrated in the accompanying drawings,forming a part thereof.

The invention relates to apparatus for cooking candy and the object oithe invention is to provide an improved form of cock ing apparatus inwhich the heat required is obtained by the use of steam.

The invention has aespecial reference to the production of the class ofcandies known as boiled goods or hard goods, and apparatus for theproduction of these candies 1S illustrated in the accompanying drawings,wherein-- Figure 1 shows the apparatus in side elevation with a detailof one of the parts broken away and represented in section, Fig. 2 is a,detail central sectional view of the apparatus, and Fig. 3 is a rearelevation of the same with some of the parts shown in section.

in carrying out the invention the parts of the apparatus are desirablyassociated upon an integral frame comprising a door plate, 10, thestandards 11, 12 and a pedestal 19. Preferably a diagonal brace, as 1t,has its opposite ends bolted to one of the standards 11, 12 and thepedestal 13, whereby each of these standards is connected with thepedestal about mid-way of the height of these parts. A shelf 15 ispreferably also provided. As shown this shelf is formed integral withthe pedestal 13 adjacent the lower end of the same and extendsrearwardly and laterally therefrom.

A tilting kettle 16 having a steam jacket 17 is hung between thestandards 11 and 12. For supporting the kettle upon the standards,trunnions, as 18, 19, provided at opposite sides of the kettle arejournaled in the standards adjacent thehigher ends of the same. Thetrunnion 19 is desirably made tubular and is rigidly mounted upon thewallof the kettle above the steam jacket 17. A nipple 20 for connectionwith a steam supply pipe (not shown) extends. into the bore of ermit thetrunnion to rotate about this nipp e during the tilting of the kettle,the nipple is swiveled in the trun nion and is packed to provide againstleakage of the same. standing flange 21 is formed upon the nipple at itsinner end and a packing gland 22 surrounds the stem of the nipple andhas threaded connection with the wall of the trunnion. A nut 23 appliedto the outer end of the nipple 20 serves for compressing a quantity ofpacking material, as 24, between the inner end of the gland 22 and theflange 21.. A pipe 25 extends between the trunnion 19 and the steamjacket 17. The bore of this pipe communicates with the bore of thetrunnion and a chamber of the steam jacket 17 for conveying steam to thejacket. if desired, a valve 26 may be mounted in the pipe 25 forcontrolling the passage of steam therethrough. The trunnion 18 isdesirably also made tubular and serves as a bushing for a shaft 27. Asshown, this shaft extends through the adjacent wall of the kettle l6 andhas itsend rotatably seated against a tubular boss 28,'which is formedupon the inside wall of the kettle in line with the bore of the trunnion19. lhe opening through the boss 28 communicates with the bore of thetrunnion 19 and the shaft 27 is made tubular for a portion of its lengthto permit of the admission of steam into a coil 29 which is carried bythe shaft. To prevent leakage of steam between the boss 28 and theadjacent end of the shaft 27, provision is made for packing the jointbetween these parts. As shown, a flange 39 is formed upon theadjacent'end of the shaft and a clamping ring 31 extends over thisflange and has threaded engagement with the exterior sur face of theboss 28. The coil 29 rotates with the shaft 27 and serves both forstirring and heating the contents of the kettle. A pulley 32 ispreferably mounted upon the outer end of the shaft 27 for receivingpower to turn the same.

A steam discharge pipe 33 extends laterally away from the trunnion 18,at a point between the standard 11 and the adjacent side of the kettle.This discharge pipe is preferably made flexible to permit partialrotation of the trunnion 18 incident to the tilting of the kettle. itmay serve both to receive steam which is assed through the coil 29, asalso the (ischarge from the jacket 17. That which has assed through thecoil 29 reaches the disc arge pipe 53 by transversing the bore, as 34 ofa-tubular part of the shaft '27 and a lateral o ening which is providedin the shaftin line As shown, an annular outwith the discharge pipe 33.To provide communication between the lateral opening and the dischargepipe 33 at all times irrespective of the rotation of the shaft 27, anannular groove 36 is formed 1n the wall of the trunnion 18. Thedischarge from the kettle 17 reaches the pipe '33 through a pipe 37which has one end connected with the foot of the steam jacket 17 and theother end connected with the trunnion 18 in line with the annular oove36.

Leakage of steam about the shaft 27 and into the open air through theouter end of the trunnion 18 is prevented by packing the shaft at thepoint where it leaves the trunnion. As shown, a gland 38 surrounds theshaft 27 and has threaded connection with the outer end of the trunnion18. Leakage of steam about the shaft 27 and into the kettle 16 isprevented by also packing the shaft at the inner end of the trunnion. Asshown, an annular rib, or flange 39, is formed on the shaft 27 adjacentthe inner end of the trunnion and a gland 40 surrounds the shaft 27 andhas threaded engagement with the trunnion. To permit the assembling ofthe parts, the shaft 27 is conveniently made in two sections, onesection, as 41, being located within the kettle 16 and serving to carrythe coil 29 and the other section, as 42, extending through the trunnion18. These sections are connected by a union 43.. If desireda drain cock44 may be provided in the pipe 37 adjacent the bottom of the kettle.

In some instances it may be desirable to treat the contents of thekettle 16 under vacuum. For this purpose a hood 45 adapted to makesealed engagement with the rim of the kettle 16 is provided. As shown,the rim of the hood 45 and kettle 16 are each reinforced by a ring, as46 and 47. These rings have a complementary tongue 48 and groove 49, thelatter being partially filled with a packing material 50. A plurality ofclamps 5], serve for securing the rings 46 and 47 in engagement.

To permit the hood 45 to be conveniently lifted out of engagement withthe kettle 16, the hood is carried by a bracket arm 52 which is hingedlyconnected to the top of the pedestal 13. As shown, the pedestal 13 isbifurcated adjacent its higher end and the bracket arm 52 extendsbetween the arms, as 53, 54 of the pedestal and has trunnions, as 55,56, which are journaled therein. The bracket arm 52- has an upstandingtubular head 57, the bore of the head being extended laterally throughone of the trunnions, as 56. The passage thus formed communicates withthe chamber of the hood 45 through a goose neck 58, which extendsbetween the top of the hood and the top of'the bracket head 57 and hasits opposite ends firmly bolted to these parts.

A condenser 59, and pump 60, serve for exhausting the chamber of thekettle and hood when these parts are in sealed engagement. The pump 60and the motor 61 for driving the same are conveniently mounted upon theshelf 15. The motor 61 and pump 60 are operatively connected, as byinteruieshing gears 62 and 63 mounted on the spindles of the motor andpump, respectively. The condenser 59 is conveniently located directlyover the pump 60. A standpipe 61 leading out of the lower end of thecondenser serves both for connecting the chamber of the condenser withthe chamber of the pump and for supporting the condenser. A water supplypipe 65 leads into the top of the condenser 59 and communicates with aspray head 66, which is located within the chamber of the condenseradjacent its higher end. As is usual in devices of this kind aforaminous plate or screen 67 extends across the chamber of thecondenser intermediate its ends.

An exhaust pipe 68 has swivel connection between the outer end of thetubular trunnion 56 and the bracket arm 52 and leads therefrom into theside of the condenser 59 above the screen 67. To provide a tight jointbetween the end of the exhaust pi )e 68 and the trunnion 56 while stillpermitting the rotation of the latter incident to the raising andlowering of the hood 45, the end of the trunnion is formed with a socket69 for receiving the end of the exhaust pipe and the latter is providedwith a circumferential flange or bead 70. A gland 71 which slides uponthe exhaust pipe 68 is screwed into the socket 69 and serves forcompressing a quantity of packin material 72 against the flange or head70.

Sight glasses 73, 74 and a relief valve 75 are desirably mounted in thehood 45. As shown, the hood also carries a thermometer 76 and pressuregage 77, the former having its stem 78 extended downwardly to enter thechamber of the kettle 16, when the hood and kettle are connected. Thehandle 79 is secured against the front of the hood for lifting the same.Similarly a handle 80 is mounted on the wall of the kettle for tiltingthe kettle when the hood has been raised. Provision is desirably alsomade for supporting the hood 45 in horizontal position in event thekettle has been removed from between the standards 11, 12. As shown, afixed bracket arm 81 extends upwardly and forwardly from the pedestal l3and a set screw 82 extends vertically through the outer end of the samefor engagement with the under side of the tilting bracket arm 52. Thecoil 29 is preferably so formed that the intermediate turns of the sameare of greater diameter than the turns adjacent the ends of the coil.The outline of the coil thus conforms in shape with that of the kettle16.

- kettle,

macaw being connected with an adjacent part. of

the coil for supporting the same.

During the operation of the apparatus, the shaft 27 will be rotated.This serves to revolve the coil 29 within the chamber of the kettle forstirring the contents of the kettle and bringing all parts of the coilinto intimate contact therewith. Steam supplied through the nipple 20will ass through the coil 29 and through the jac et 17 of the kettle orthrough the former alone if the valve 26 be closed, Usually the contentsof the kettle will be partially cooked while the kettle is open. Thehood will then be lowered and the contents of the kettle subjected toany desired degree of vacuum by admitting water to the chamber of thecondenser 59 through the water suppl pipe 65 and by operating the pump60. en the cooking operation has been completed, the

relief valve 75 will be opened, the clamps 5l loosened and the hood t5raised. The kettle 16 may then be tilted for emptying'the contents ofthe same upon a slab.
